Android Question Countdown timer notification

[mohsen10024]

Hello everyone.
I have an app that has a countdown timer notification. I wanted to make this notification. I made the countdown timer part, but how to put the countdown timer in the notification so that the timer works in the notification.
Thankyou.

There are two relevant examples here: NB6 - Notifications Builder
The progress indicator and the one the one that changes the notification icon.

Hi Earl. Thank you for replaying.
I did this, but now the notification stops, both in open screen mode and in locked screen mode, I even created a service for it, but it stopped again.
What do you suggest?
